Ls400 Wheel And Tyre Combinations

[Keith Bowler]

I have a 1999 LS400 with DHP and just wondered what peoples views are on wheel size and tyre combinations.

I am probably going to stick with the standard 17" DHP wheels but not entirely sure about tyre profile and widths.

I have 45 profile 235's on it at present and the ride is a bit hard.

I have just acquired a set of nicely refurbed identical DHP wheels with 50 profile 245's which I assume might soften the ride a bit albeit the rolling circumference will be greater so my speedo will be out but I'm not fussed about that as it will over read rather than under read.

I'd be interested to hear any views or experiences other members may have.

Hi

The pirelli p zero 245/50/17 was the standard width and profile for DHP wheels but they are only availible from limited manufactures and they are expensive.

the 235/45 tyre will actually make you speedo read faster, when showing 60mph your actual speed will be 57mph http://www.miata.net/garage/tirecalc.html.

The best option i found was to fit 225/55/17 tyres, they keep the speedo acurate, they have a large enough sidewall to keep the car comfortable, they handle better than the stock 225/60/16 LS400 tyres and they are availible from a large number of manufactures.

before i moved on the my LS430 i ran mine with dunlop SP01 tyres which were standard on the 1st gen LS430 and founf them to be good overall but most important on the LS they were quiet.

Hope this helps
